You can use the -unab- command (or tsunab if you are using time-series
operators), mixed with a macro function:
An example could be:
unab allvars : int_*
unab excludedvars : int_abc int_xyz
local selected : list allvars - excluded
And then you use the local macro -selected- like this:
reg y x1 x2 `selected'
You will see that the results do the same as (int_* - int_abc - int_xyz)
Cheers,
Sergio
PS: Its not in one line, but after you create the macro you can use it
everywhere, from summ to xtprobit

Dear Statalisters,
How can I do the following?
reg y x1 x2 (int_* - int_abc - int_xyz)
Obviously the above doesn't work.
"(int_* - int_abc - int_xyz)" is supposed to mean the varlist of all
variable names starting with int_ except int_abc and int_xyz, and in
place of int_abc and int_xyz could be any other variable names that I
specify.
I would need this syntax to be part of the varlist that goes with any
estimation commands such as -reg-, -probit-, etc.
Thanks.
Kelvin.
